Singles by the Warblers, with series stars Darren Criss and Chris Colfer performing lead vocals, have collectively sold over 2 million copies.

[citation needed] In 1999, the group made an appearance on the Late Show with David Letterman and performed at Fenway Park for the crowd at the Major League Baseball All-Star Game.

The Bubs Foundation, Inc. is a 501(c)(3), not-for-profit organization founded in 1991 by Beelzebubs alumni to "awaken in young people a passion for expression and learning through music".

[9] The organization consists of alumni and friends of the Beelzebubs dedicated to the Bubs Foundation mission to raise money for the music programs of Boston-area public schools.

The ten covers, plus two others recorded with the Bubs that did not appear on the show, were included on an album, Glee: The Music Presents the Warblers, which was released on April 19, 2011, and debuted at number two on the US Billboard 200, selling 86,000 copies in its first week.

[13] A thirteenth song on the album by the Warblers did not involve the Bubs: "Blackbird" by The Beatles was covered by Chris Colfer with other background vocalists.

[17] Like Shedding before it, Pandaemonium also swept the four all-male categories of the Contemporary A Cappella Recording Award, including Best Album, Best Song, Best Solo and Best Arrangement.
